SPECIFICATION forming part of Letters Patent No. 314,572, dated March 31, 1885.

1 Application led ScptemberlO, 1884. (No model.) I

To all whom t may concern,.-

United States, residing at Philipsburg, in the -county of Centre and State of Pennsylvania,

have invented a new and useful lImprovement in Wrenches, of which the follcjwing isa specification, reference being had to the accompanying drawings.

'Ihisinvention relates to wrenches, and to that class of the same which employ a sliding jaw; and it has for its object to provide a device of Ithis character which shall possess superior advantages in point of simplicity and durability in construction,and convenience and eficiency in operation.

A further object of the invention is to provide a Wrench for turning nuts which shall be capable of various adjustments, and which shall have a firm hold on the article to be turned, so that there will be no possibility of its slipping when in operation.

With these ends in view the said invention consists in certain details of construction and combination of parts, as hereinafter set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of our improved wrench, showing the latter in its open position. Fig. 2 is a rear View of the same in the closed .position. j Fig. 3 is a longitudinal section on the linear w, Fig. 2. Fig. 4 is a transverse section on the line I/ y, Fig. 8. Fig. 5 is a transverse section von the line .e a, Fig. 3.

Like letters are used to indicate corresponding parts in the several gures Referring to the drawings, A designates the shank of our improved wrench, having a stationary jaw, B, formed therewith at one end, and a handle, C, at the opposite end.

I) designates a sliding stem working in guide-loop E, projecting from the stationary shank A, and carrying a sliding jaw, F, at one end, said stenivbeing arranged parallel to and sliding upon the shank. A band or collar, G, clasps the other end of' the stein and encircles the shank, an opening, a, being formed in the latter to allow the passage of a pin or bolt, H, headed at each end, as at b d, the head b working through an opening in the band or collar G,

and the other end passing through an opening,

e, of the band or collar, and an elongated slot,

f, of an adjusting-piece, I. A coiled spring,

J, is arranged inthe opening a of the shank,

and bears at one end against the head b ot' the" pin H, and at the other end against the inner face of the shank. tension of this spring serves to hold 'the head d against the adjusting'piece I, to retain the latter in the position to which it may be adjusted. The -adjusting-piece I lies iiat against the face of the band or collar G, and' has one of its ends turned or curved outward to form a bearing-edge, g, for the thumb, its other end being turned inward at right angles, as at h,

It will be seen that the a stud or pin,- K, extending inward from said end h, and passing through an opening, t', in

the band or collar G, entering any one of aI other end of the connecting-bar being pivoted f' within the slotted upper end of the operating handle or lever N. The latter is curved at the upper end, and is pivoted'to the lug or projection O, which extends from the sha-nk A, and when not in operation it rests flat against the handle end of the shank.

The operation of our invention will be readily understood from the foregoing description, taken in connection with the annexed drawings.

In applying our improved wrench for turning nuts, the handle or lever N is drawn out, as seen in Fig. l, so as to cause the stem D to slide upward, when by the inward movement of the handle or lever the stein D is caused to work downward, and its jaw clasp, in connection with the jaw of the shank, the article to be turned. Should the space between. the two jaws be insufficient to clasp the article, the sliding stem may be adjusted farther up by sliding the adj ustingpiece I until its pin or stud K is withdrawn from the hole in the adjustable plate L. The latter is then set farther I OC) io junction to engage the article to be turned.,

The spring `inclosing the pin or bolt H serves to hold the head d against the adjusting-piece I I, so that in adjusting the latter it is not nec-l 2o, pins or bolts n. the latter serving as a means essary to loosen and then tighten a screw, as in the former method of adjustment, since the piece I may be slid in and out by simply removing the pressure of' thehead d of the bolt I-I Vagainst said piece, the spring returning the bolt to its original position. The jaws B F have a hole, m, pierced through each to receive of attaching Wearing-plates p 1a, which are U-shaped in crosssection, as seen in Fig. 5. The said plates p have teeth o, which engage With the articlevto be turned., By this arrangement-We may detach the plates 19, they'teeth of which are coarseand substitute therefor' plates of the same form havingvner teeth when turning small articles. l/Ve may also attachplates concave incross-section and of snch a forni as to bejapplicable in turning pipes and the like, and for this reason we do notwis'h to be limited to the character of the plates or the .form thereof which may beat- .tached to the jaws of the Wrench. Our improved Wrench is simple in construction, convenient in operation, and efficient in use. By means of the same we are enabled to accommodate the wrench to various sizes ofnuts or otherL articles to be turned. The Wrenchafibrds a firm hold on the articles, and there will be no chance of slipping the hold when in operation. The action is positive and certain, and the arrangement is such that `dle or lever, as set forth. I- p 4. In a wrench, the comhinatiomwith the-- there is no possibility of its Working out of order. v l l Having described our invention, We claim- 1. In a wrench, the combination, with the shank carrying a jaw at one end, of a sliding Stem Carrying a jaw, a pivoted. handle Orleyer, and umeans, substantially as-described,

for connecting the latter with the stem, said means being adjustable in length, as and for the purpose setforth.

2. In a wrench, the combination, with the shank carrying a jaw at one end, of the stem sliding on said shank and carrying a jaw, a band or collar rigidly held to the stem and -slidin-gon-the' shank, the pivoted handle or lever, the adjustable plate connecting with the handle or lever, and means for attaching theplate to the stem at` any point of 'the length of said plate,- as s et forth.

, 3. Ina wrench, the combination, with the 'shankv carrying ajaw, fof thestem sliding on saidshank and carrying a jaw, the pivoted handle o 'r lever, a perforated 'plate held at any point of its length on thestem, and a connectingebar for attaching the plate tothe han-- shank'carrying a jaw, of the lstemsliding en the'shank, andalso carrying ajaW, 'a band or collarl vconnecting the shank and stem, a spring` pressedpin or bolt secnring the hand to the stem, an adjusting-piece heldin place by the head of the said bolt, a pin on one end of the said piece, a perforated plate arranged to he engaged by the said pin, and a handle or lever connecting with the plate, as set forth. y

In testimony that we claim the foregoing as' our 'own We have hereto aiiixed our signatures in presencerof two Witnesses. n A,
